3	CONSTRUCTION LAYOUT TOOL	PCT/US2009041450	2009-04-22	WO2009132138A3	2010-03-11	CERWIN CHAD WILLIAM
A layout tool is provided for anchoring a layout line, such as a chalk line, in relation to a piece of construction material. The tool (100) generally includes a top plate (102) and a depending plate (106). Angular markings (104) are provided on the top plate (102) to indicate angles, pitches, or the like. The tool (100) further includes an anchor post (110), a spike (108), and a window or opening (112). A construction worker can align the tool (100) with a mark on the construction material by viewing the mark through the opening (112). The worker can strike the plate (106) so that the spike (108) penetrates a side surface of the construction material to secure the tool (100) in the desired position. A chalk line can then be attached to the post (110) and extended a desired length across the construction material in a desired angular orientation by using the markings (104). The chalk line can then be snapped against the construction material to provide a desired layout chalk line.

5	PROTRACTOR UNIT FOR DRAWING-BOARD	PCT/EP1979000034	1979-05-11	WO1979001076A1	1979-12-13	ALPIA SA
On the head of a conventional drawing apparatus, ratchet means consist of a toothed circular plate (1) integral with the rule-carrier, a circular plate (2) integral with the turning handle, the plates (1, 2) being concentric and rotating in a same plane, and a third toothed plate (3), forced towards the rules by springs (4) which mesh on the plates (1) and (2) making them integral with each other. This plate (3) is movable along a hub (E), perpendicularly to the axis of said hub; it may be disengaged from the plates (1) and (2) by exerting a pressure on a pusher (5) which actuates a lever (6) which lifts a small plate (7) connected to the small disc (3) by columns (8).

9	AUTOMATIC PALLET-MAKING MACHINE AND METHOD.	EP82901800	1982-04-15	EP0078308A4	1984-11-16	BELCHER ROY L
A pallet is automatically assembled and nailed together on a horizontally reciprocating carrier (10). The carrier (10) moves in a forward direction beneath a slat dispenser (14). A first series of one-way trip dogs (54) mounted on the carrier (10) successively removes the bottom slat (9) from a stack of slats held by a dispenser (14) to deposit a series of slats (9) onto the carrier (10) to form the bottom deck of a pallet. The carrier (10) has stringer engagement levers (80) which engage the ends of a series of stringers (8) held in dispensers (16). The carrier (10) reverses direction after deposit of the bottom series of slats (9) and each stringer engagement lever (80) pulls a stringer (8) from the dispenser (16) with each stringer (8) positioned transversely to the previously dispensed slats (9). As the carriage (10) moves in the reverse direction, another series of one-way trip dogs (54) mounted on the carrier (10) successively dispenses a second series of slats (7) to form the top deck of the pallet. The carrier (10) with the laid-up pallet next moves to a nailing station (18) where nailers (130) automatically fasten the top and bottom slats (7 and 9) to the stringers (8). The carrier (10) then moves to a ratcheted bottom-stacking device (20) which removes a nailed pallet from the carrier (10) and adds that pallet to the bottom of a vertical stack of pallets.

Sur une tête d'appareil à dessiner classique, les moyens d'encliquetage sont constitués par un plateau circulaire denté 1, solidaire du porte-règle, un plateau circulaire 2 solidaire de la poignée tournante, les plateaux 1,2 étant concentriques et tournant dans un même plan, et par un troisième plateau denté 3, poussé vers les règles par des ressorts 4 qui s'engrène sur les plateaux 1 et 2 en les rendant solidaires. Ce plateau 3 est mobile le long d'un moyeu E, perpendiculairement à l'axe dudit moyeu : il peut être dégagé des plateaux 1 et 2 en exerçant une pression sur un poussoir 5 qui actionne un levier 6 lequel soulève une plaquette 7 reliée au plateau 3 par des colonnes 8.

A double-sided miter box, which may be fastened for example on the rolling truck of a panel saw, has two stop rails which can swivel around an axis of rotation. A measurement value generator for determining the swivelling position consists of a magnetically coded measurement ribbon arranged between the stop rails around the axis of rotation along a graduated circle, of a fixed sensor which contactlessly scans the measurement ribbon and of a display for the measurement values.
